Epiphyllum oxypetalum, Haw. (Phyllocactus grandis, Lem.). Very large, sometimes 20 ft. long, with numerous short side branches, and these in the same plane with the main st., thin and lf.-like: fl. large (nearly a foot long), white, night-blooming (sometimes described as day-blooming). Originally from Mex., but said to be found in Honduras and Guatemala; also reported from Cuba, but surely not native there.—One of the commonest and best species in cult.

Stems erect, ascending, scandent or sprawling, profusely branched, primary stems terete, to 2-6 m long, flattened laterally, ligneous at base, secondary stems flat, elliptic-acuminate, to 30 cm x 10-12 cm, thin; margins shallowly to deeply crenate and ± undulate. Flowers produced from flattened portions, to 30 cm long, 12-17 cm wide, nocturnal, very fragrant. The principal odor component in the aroma is benzyl salicylate; pericarpel nude, slightly angled, green, bracteoles short; receptacle 13-20 cm long, 1 cm thick, brownish, arching, bracteoles narrow, ca 10 mm long; outer tepals linear, acute, 8-10 cm long reddish to amber; inner tepals oblanceolate to oblong, acuminate, to 8-10 cm long and 2,5 cm wide, whitish; stamens greenish white or white, slender and weak; style greenish white or white, 4 mm thick, as long as inner tepals, lobes many, pale yellow or white..

Cultivation

An easily cultivated, fast growing epiphyte^wp. Needs compost containing plenty of humus and sufficient moisture in summer^wp. Flower best when pot-bound^AH. Should not be kept under 10°C (50°F) in winter^wp. Can be grown in semi-shade or full sun. Extra light in the early spring will stimulate budding^wp, but over watering will cause bud drop^sn. Giant, up to 10 inch flowers in late spring or early summer and large specimens can produce several crops of flowers in a season^wp. Fertilize with low-nitrogen fertilizer before and after flowering^sn.

Propagation

Cutting should root pretty easily in spring and summer. Allow cutting wound to dry for a couple of days before planting.

Pests and diseases

Fungal leaf and stem spot, mealybugs, scale insects^AH.
